Be it knoWn that we, LA\VIENCE B. J ENQKES andJomx SonmnnnG bthCitizensof the United Stte ,tesidifig atWorces ter, in the county ofWorst-id state of Massachusetts, have invented a new and nseful TubeFiaine foililoqdette Loo1ns, of Which the 'follxving*is a spcification.

This invention relates to the tube rames which are used in large numbersininoqnete looms. Present conditions demand that the frames be of muchgreater length than has been heretofore customary. It is essential thatthe longitudinal alignment of the tube trames be acourately preserved,partioularly during the delivery of yarn therefrom, and it is the objectof our invention to provide means for stiffening the tube frames andinoreasing tl1eir resistanceto vertical defiec tion.

OUI invention further relates to arrange mente and combinations of partswhi oh Will be hereinafter described and more pa1tiou larly pointed outin the appended claims.

Preferred forms of our invention are shown in the drawings in which:Fig. 1 is a side elevationof one of our improved tube frames;

Fig. 2 is apartial side elevation of the stiflening members for theframe shown in Fi. 1; igs. 3 and 4 are seotional views taken along thelines 33 and 41 in Fig. 1; Fig. 5 is a partial side elevation of amodification; v

F ig. 6 is a bot-tom view thereof; Fig. 7 is a sectiohal view t-akenalong the line 7-7 in Fig. 5. A

, -Referring to the drawings, we have shown a tube frame comprising ahollow rectangular bar 10, to the side of which the yarn tubes 11 are'secured in the usual manner. Bearing brackets 12 are mounted on theends of the bar 10, and intermediace bearings 13 are secured to theupper side thereof, these bearings supporting 011e or more yarn spools14. The general arrangement of the parts thus far desoribed is shown inthe prior patent to Hutchins No. 1,065,871 issued June 24-, 1913, towhich reference is made for a more detailed description.

The braokets 12' may be provided with 'inwardly extending plates 01''arms 15 recived within the.eds. ofthdh0llow bar 10. These arme fitolosely Within th bar and may be seoiifed thereiri by scieWs 16. It is--de'sirable to use' fiat or eounter-suiik had sor'evvs, and in order toprovide sufiioierit tlnokness to recive the heads of s'ucl1 sorews,

bar 10. These stifening members are oom monly in the form of long woodenwedges reversely disposed within the hollow bar. The Wedges are insertedfrom the ends to the bar, and are driven toward eachother until they arefirml'y Seated within the bar, after which a screw 19 may be inserted toprevent their displacement. This screw may also serve as one of thefastenings for an intermediate bearing 13.

In Figs. 5, 6 and 7 we have shown a slight modification in which thewedge-shaped stifiening membrs 20 engage the sides ofth9 bar 10 insteadof the top and bottom there- One. or more sorews 21 extend through theside of the bar and aot to hOld the members in place. v

Having thus desoribed our invention, the advantages' thereof Will bereadily apparent. The stifiening members 18 or 20 may be made of pine orother light wood and add very little to the weight of the frame. Theyproduce a marked efieob, however,upon the stifiness of the tube framesand they also aot to reduce the vibration t-hereof.

It will be further evident that changes and modifications may be made inour construction within the spirit and scope of our invention assetforth in the claims, and we do not Wish to be otherwise limited tothe details herein disclosed, but what we claim 1. tube frame for amoquette 100m com- 3risin a hollow rectanular bar t0 Whicli yarn tubesare seoured, means to support yarn spools thereon, and means to st1fleusaid bal, said means comprising longitudinal1y extending reversedwedge-like membe1s firml seated therein.

9. A tube frame for a moquette loo1ncomprising a hoHow re ctangn1ar barto which yarn tubes areecured, means to support yarn spools thereon, andmeans to stifen said bar, said means comprising longitudina1ly extendingtape1ed wood strips reversely disposed in said bar.

3. A tube frame for a moquette 100m comprising a hollow rectangn1ar barto which' yarn tubes are secured, means to support yarn spools thereon,and means to stiffen said bar, said means comprising longitudinallyextending reversed wedge-lke members firmly seated therein, and means tohold said strips fron1 displacement.

4. A tube frame for a moquette 100m comprising a hollow rectangular barto which yarn tubes are secured, means to support yarn spools thereon,and means to stifen said bar, said means co1nprising longitudinallyextending reversed wedgelike membe1s firmly seated therein, and firnflyengaging the upper and iower walls 0:E said 5. In a tube f1ame, a hOHOWbar, a spoo1- holding bracket having arms extending int0 said bar, saidarms each having a depressed portion and having also a threaded h0le insaid depressed portion, and screws extending through the wa11s of saidbar and threaded in said openings to secure said bracket in position.

In testimony whereof we have hereunto afiixed our signatures.
